Insulating refractory castable
VITCAST 1200INS & Gun Mix
A very lightweight insulating refractory castable, designed for use as backup insulation in low-temperature applications. Offers excellent thermal insulation with minimal weight, helping to reduce heat loss and overall lining mass.
Examples of Applications: Typically used between the outer casing and refractory lining in boilers, flues, stacks, and other applications where a lightweight insulating layer is required.
